Tourbograph Perpetual «Pour le Mérite»

A. Lange & Söhne reserves its "Pour le Mérite" collection for its most technically accomplished creations. The fifth timepiece to join the range, the Tourbograph Perpetual brings together a constant-force fusee-and-chain transmission, a tourbillon escapement, a split-seconds chronograph, and a perpetual calendar. An impressive accomplishment that A. Lange & Söhne has endowed with a most classic style. The dial with its Arabic numerals, railroad minutes and blued steel or rhodium-plated gold hands, and the trefoil arrangement of the subdials are a tribute to the Manufacture's famed pocket watches. This traditional approach is also evidenced in the construction of the movement, such as a column-wheel transmission for the chronograph and a screwed balance.
